I am planning to put in a concrete widewalk around the corner of my house. I want to have a wood gate at the corner. Do I first put in the gate and pour the sidewalk around the posts or lay the concrete and attach the posts after.

The rule of thumb I know that applies here tells me to use at least 6"x6" posts for wide gates concreted into a 3ft deep hole. By preference I'd go for a single larger post and go deeper than you suggest. You might get away with firmly bolting the two posts together, but I would be wary about compromising on the depth...
My first thought is a guy wire from the top corner of the post, with a turnbuckle in the middle to tension it up and pull out that lean in the post. It seems that if you don't do something like this, the only alternative IS to reset the posts, which is a lot of work. Hope this helps.
This is what a turnbuckle looks like:

The posts for your gate should be embedded in a good concrete base 2 to 3 feet deep. If the gate posts are going to be inside the edges of your walk, then I would install them first. It goes without saying that you should use PT posts and be sure the top of the concrete around the post bevels slightly away from the post so water will run away and not pond around the wood.
